SPECIFICATION forming part of Letters Patent No. 344,607, dated June 29,1886.

Application tiled October 30, 1885. Serial No 181,356. (No model.)

To all whom it mmy concern.-

Be it known that 1, ANDREW J. UPHAM, a citizen of the United States,residing at Sycamore, in the county of De Kalb and State of Illinois,have invented certain new and useful Improvements in Fence \VireTighteners; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the ac companying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

Myinvention pertains to fence-wire tighteners; and it consists moreespecially in certain novel mechanism for forcibly drawing the wire.

In the drawings, Figurel is a side elevation of a machine embodying myinvention. Fig. 2 is a detached view of the pawl (J. Fig. 3 is a partialcross -section through the pivotal point of the lever E. Fig. 4 is adetached view of the dog D. Fig. 5 is a cross-section in the line :0 a"of Fig. 1.

A is a bar, fastened in any suitable manner to the fixed object A, andprovided also with the usual clamp, A for use in case it is desired todraw two wires together. The bar A is further furnished with notches aon its upper surface, and with the fixed sleeve or clip I), at or nearits inner end, partially to encircle and loosely to hold the parallelbar B.

B is a bar, furnished with the usual grip, g, at its outer end,to clutchthe wire to be drawn, and held substantially parallel with and againstthe side of the bar A, by being passed through the sleeve 11 on thelatter, and pivoted at Z on the inner face of one of the vertical platesconstituting the lever E.

E is a hand-lever constructed of the two plates E,placed,respectively,on opposite sides of the two bars Aand B, and heldtogether bya bolt, 6, passing through the plates E, below both of saidbars, and by the bolt h, near the top of such plates, which forms thepivotal seat of the pawl C. It will be noticed (Fig. 3) that the portionof the bolt 6 between the plates E has two different diameters, thelarger diameter, e, serving as a support for the bar A and the lesserdiameter, 6 as a seat or support for the bar B. The lower seat orrecess, e", is necessary to permit the movements of the bar B relativeto the position of the lever E in the oscillations of the latter. Itwill also be noticed that the pivotZ does not extend beyond the innerface of the bar B, Fig. 3, and therefore the space is left for the bar Ato lie loosely along the inner face of the bar B and rest down upon theseat 6'.

D is a dog pivoted near theinner end ofthe bar B, and to the outer faceof the latter, and adapted, by means of a lateral lug, d, to engage thenotches a reversely and alternately with the pawl O. A stop, d, isformed on the inner edge of the dog D, at such location as to strike theupper edge of the bar B and prevent the dog D from falling or beingdragged by the pawl 0 too far outward. ,The pawl O is pivoted, as shown,in the upper end of the lever E, having its engaging end outward, toengage the notches a, and its opposite or inner end projected over thelug d of the dog D. A recess, a, is formed in the lower surface of thepawl O, in which the lug d passes during the process of tightening.

The operation of myinvention is as follows: The respective ends of thebars A and B having been attached, as shown, the oscillation inward ortoward the fixed point A of the lever E will cause the outer end of thepawl G to engage one of the notches a. This attachment then serves as afulcrum for the lever This engagement of the pawl O is assured by theinward movement of the lever E slightly lifting the inner end of the barB, and thus forcing the dog D upward against the inner end of the pawlO, causing the outward or engaging end of the latter to enter the notcha. \Vhen this engagement is effected, the further movement of the leverE toward thepost a carries the bar B and the wire to be tightened inthat direction. When the lever E has been forced to the inner limit ofits oscillation, the dog D engages reversely an adjacent notch, a, andholds the bar B, while the outward oscillation of the lever E draws thepawl O inward to the next notch a, when the operation just described isrepeated. Thus the bar B is caused to draw the wire attached thereto toward the point of attaching the latter. If one complete draw is notsufficient, the wire can be temporarily held in any suitable manner andanew grip thereon taken.

What I claim as my invention. and desire to secure by Letters Patent ofthe United States,

1. The combination of the bar A, provided with the notches ayclip b, andmeans for end attachment, the bar B, held in such clip and pivoted tothe lever E, and provided with the dog D, and with means for grippingthe wire, the lever E,inclosing the bars A and B, and the pawl O,wherebythe inner end of the bar B is adapted to rise independently of the barA, so as to cause the engagement of the pawl 0, substantially as shown,and for the purpose specified.

2. The combination of the bar A, provided with notches a, the barB,unilaterally pivoted to the lever E, and provided with the dog D, thelever E,inclosing both of said bars, and the pawl O, pivoted to suchlever and adapted'to be actuated by the bar 13, substantially as shown,and for the purpose described.

3'. The combination of the lever E, bars A and B, and the bolt 0, thelatter having variant diameters .whereby a different seat is providedforeach of said bars, substantially as shown, and for the purposedescribed.

In testimony whereof I affix my signature in presence of two witnesses.

ANDREW J. UPHAM.
